DGS-3100 Series Gigabit Stackable Managed Switch CLI Manual

1 INTRODUCTION

The DGS-3100 series of products family consists of 24 / 48 -port 10/100/1000Base-T PoE / NonPoE L2 Stackable Management Switches with 4 Combo SFPs and DGS-3100-24TG, a switch with 16 SFPs and 8 copper GE ports.

The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The Command Line Interface (CLI) can be used to configure and manage the Switch via the serial port or Telnet interfaces.

This manual provides a reference for all of the commands contained in the CLI. Configuration and management of the Switch via the Web-based management agent is discussed in the Manual. For detailed information on installing hardware please refer also to the Manual.

Accessing the Switch via the Serial Port

The Switch’s serial port’s default settings are as follows:

9600 bps

No parity

8 data bits

1 stop bit

A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above is then connected to the Switch’s serial port via an RS-232 DB-9 cable.

With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not appear, try pressing Ctrl+r to refresh the console screen.

[

Figure 1–1 Initial CLI screen

The initial username is admin (lower case). Press the Enter key twice to display the CLI input cursor. This is the command line where all commands are input.

Setting the Switch’s IP Address

Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default Switch IP address to meet the specification of your networking address scheme.

The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, but can be found on the initial boot console screen – shown below.

1


Figure 1–2 Boot Screen

The Switch’s MAC address can also be found in the Web management program on the Device Information window on the Configuration menu.

The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.

The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:

1. Starting at the command line prompt, enter the commands config ipif System vlan default ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy. Where the letter x represents the IP address to be assigned to the IP interface named System and the letter y represents the corresponding subnet mask.

2. Alternatively, enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the letter x represents the IP address to be assigned to the IP interface named System and the letter z represents the corresponding number of subnets in CIDR notation.

The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a management station to the Switch’s Telnet or Web-based management agent.

Figure 1–3 Assigning an IP Address

2


In the above example, the Switch was assigned an IP address of 1.1.1.10 with a subnet mask of 255.0.0.0. The system message Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet, SNMP MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

NOTE: The DGS-3100 series of switches have the capability to be configured to have no IP address. This function maybe used to disable Layer 3 functions of the Switch. When the IP address is disabled, the Switch can only be managed through the console port. Other management applications such as Telnet, Web-based and SNMP cannot be used to manage the Switch when the switch has no IP address.

2 USING THE CONSOLE CLI

The Switch supports a console management interface that allows the user to connect to the Switch’s management agent via a serial port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the TCP/IP Telnet protocol. The console program can be used to configure the Switch to use a SNMP-based network management software over the network.

This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation.

NOTE: Switch configuration settings are saved to non-volatile RAM using the save command. The current configuration will then be retained in the Switch’s NV-RAM, and reloaded when the Switch is rebooted. If the Switch is rebooted without using the save command, the last configuration saved to NV-RAM is loaded.

Connecting to the Switch

The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary terminal emulator program (for example, the HyperTerminal program included with the Windows operating system) using an RS-232C serial cable. Your terminal parameters will need to be set to:

VT-100 compatible

9600 bps

8 data bits

No parity

One stop bit

No flow control

The same functions may also be accessed over a Telnet interface. Once an IP address for the Switch has been set, A Telnet program can be used (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether accessed from the console port or from a Telnet interface.

After the Switch reboots and you have to logged in, the console looks like this:

Figure 2–1 Initial Console Screen after Logging In

Commands are entered at the command prompt, DGS3100#.

There are a number of helpful features included in the CLI. Entering the ? command displays a list of all of the top-level commands.

Figure 2–2 The ? Command

When entering a command without its required parameters, the CLI displays the prompt: command: config account message and the options listed below.

5


Figure 2–3 Example Command Parameter Help

In this case, the command config account was entered with the parameter <username>. The CLI will then prompt to enter the <username> with the message, command: config account. Every command in the CLI has this feature, and complex commands have several layers of parameter prompting.

In addition, after typing any given command plus one space, users can see all of the next possible sub-commands, in sequential order, by pressing the ? key.

To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous command appears at the command prompt.

Figure 2–4 Using the Up Arrow to Re-enter a Command

In the above example, the command config account was entered without the required parameter <username>, the CLI returned the command: config account prompt. The up arrow cursor control key was pressed to re-enter the previous command (config account) at the command prompt. Now the appropriate username can be entered and the config account command re-executed.

All commands in the CLI function in this way. In addition, the syntax of the help prompts are the same as presented in this manual angle brackets < > indicate a numerical value or character string. The < > can also indicate a word with a number for character allowed.

If a command is entered that is unrecognized by the CLI, the top-level commands are displayed under the Available commands: prompt.

6


Figure 2–5 Available Commands

The top-level commands consist of commands such as show or config. Most of these commands require one or more parameters to narrow the top-level command. This is equivalent to show what? or config what? Where the what? is the next parameter.

For example, entering the show command with no additional parameters, the CLI will then display all of the possible next parameters.

Figure 2–6 Next possible completions: Show Command

In the above example, all of the possible next parameters for the show command are displayed. At the next command prompt in the example, the up arrow was used to re-enter the show command, followed by the account parameter. The CLI then displays the user accounts configured on the Switch.

config stp

Purpose To setup STP, RSTP and MSTP on the Switch.

Syntax config stp {maxage <value 6-40> | maxhops <value 1-20> | hellotime <value 1-10> | forwarddelay <value 4-30>| fbpdu [enable | disable]} lbd [enable | disable] | lbd_recover_time <value 30-86400> ]

Description The config stp command configures the Spanning Tree Protocol (STP) for the entire switch. All commands here are implemented for the STP version that is currently set on the Switch.

Parameters maxage <value 6-40> − This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value aids in determining


74

that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch starts sending its own BPDU to all other switches for permission to become the Root Bridge. If your switch has the lowest priority, it becomes the Root Bridge. The user may choose a time between 6 and 40 seconds. The default value is 20.

maxhops <value 1-20> − The number of hops between devices in a spanning tree region before the BPDU (bridge protocol data unit) packet sent by the Switch will be discarded. Each switch on the hop count will reduce the hop count by one until the value reaches zero. The Switch will then discard the BDPU packet and the information held for the port will age out. The value may be between 1 and 20. The default is 20.

hellotime <value 1-10> − The user may set the time interval between transmission of configuration messages by the root device in STP, or by the designated router, thus stating that the Switch is still functioning. The value may be between 1 and 10 seconds. The default value is 2 seconds.

forwarddelay <value 4-30> − The amount of time (in seconds) that the root device will wait before changing from Blocking to Listening , and from Listening to Learning states. The value may be between 4 and 30 seconds. The default is 15 seconds.

fbpdu [enable | disable] − Allows the forwarding of STP BPDU packets from other network devices when STP is disabled on the Switch. The default is disable.

lbd [enable | disable] – To enable or disable the loopback Detection feature.

lbd_recover_timer [<value 30-86400>} – Time in second for the loop detection recorevy, it means that after this time there will be a check whether the loop still exists, if it doesn’t exist the port state will be changed to active.

Restrictions Only administrator or operator-level users can issue this command.

Example usage:

To configure STP with maxage 18, maxhops of 15, enabling lbd and defining the lbd recovery time as 55:

DGS3100# config stp maxage 18 maxhops 15 lbd enable lbd_recover_time 55

Success.

DGS3100#

config stp ports

Purpose To setup STP on the port level.

Syntax config stp ports [<portlist> | <ch1-32>] {externalcost [auto | <value 1-200000000>] | edge [true | false] | p2p [true | false | auto ] | state [enable | disable] | fbpdu [enable | disable | system]}

Description The config stp ports command configures STP for a group of ports.

Parameters <portlist> – A port or range of ports to be configured. The port list is


75

specified by listing switch number and the beginning port number on that switch, separated by a colon. Then the highest port number of the range is specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 1:22 specifies switch number 1, port 22. 1:3-22 specifies all of the ports of switch 1, between port 3 and port 22 − in numerical order.

<ch1-32> − a port-channel.

externalCost − Defines a metric that indicates the relative cost of forwarding packets to the specified port list. Port cost can be set automatically or as a metric value. The default value is auto.

auto – Automatically sets the speed for forwarding packets to the specified port(s) in the list for optimal efficiency. Default port cost:10Mbps port = 2000000. 100Mbps port = 200000. Gigabit port = 20000. Port-channel = 20000.

<value 1-200000000> - Defines a value between 1 and 200000000 to determine the external cost. The lower the number, the greater the probability the port will be chosen to forward packets.

edge [true | false] – true designates the port as an edge port. Edge ports cannot create loops, however an edge port can lose edge port status if a topology change creates a potential for a loop. An edge port normally should not receive BPDU packets. If a BPDU packet is received it automatically loses edge port status. false indicates that the port does not have edge port status. The default setting for this parameter is false.

p2p [true | false | auto] – true indicates a point-to-point (P2P) link. P2P ports transition to a forwarding state rapidly thus benefiting from RSTP. A p2p value of false indicates that the port cannot have p2p status. auto allows the port to have p2p status whenever possible and operate as if the p2p status were true. (A port that operates in full-duplex is assumed to be point-to-point, while a half-duplex port is considered as a shared port). If the port cannot maintain this status (for example if the port is forced to half-duplex operation) the p2p status changes to operate as if the p2p value were false. The default setting for this parameter is auto.

state [enable | disable] − Allows STP to be enabled or disabled for the ports specified in the port list. The default is enable.

fbpdu [enable | disable | system] − If enabled - allows the forwarding of STP BPDU packets from other network devices Disable – blocking STP BPDU packets from other network devices. System – indicates that port will behave as global switch’s fbpdu value configured. Fbpdu value valid only when STP port state is disabled or global STP state is disabled. The default is system.


Example usage:

To configure STP with path cost 19 and state enable for ports 1-5 of module 1.

DGS3100# config stp ports 1:1-5 externalCost 19 state enable

Success.

config stp instance_id

Purpose To add or delete VLANs of STP instance ID.

Syntax config stp instance_id <value 1-15> [add_vlan | remove_vlan] <vidlist>

Description The config stp instance_id command maps VIDs (VLAN IDs) STP instances on the Switch. A STP instance may have multiple members with the same MSTP configuration. There is no limit to the number of STP regions in a network but each region only supports a maximum of 16 spanning tree instances (instance 0 – is one unchangeable default entry). VIDs can belong to only one spanning tree instance at a time.

Note that switches in the same spanning tree region having the same STP instance_id must be mapped identically, and have the same configuration revision_level number and the same name.

Parameters <value 1-15> - The value of the instance_id. The value may be between 1 and 15. The Switch supports 16 STP regions with one unchangeable default instance ID set as 0.

add_vlan – Indicates that VIDs specified in the <vidlist> parameter are to be added to the STP instance_id.

remove_vlan – Indicates that VIDs specified in the <vidlist> parameter are to be removed from the STP instance_id.

<vidlist> – Specifies the range of VIDs to add to or remove from the STP instance_id. Supported VIDs on the Switch range from ID number 1 to 4094. By default each created vlan belongs to instance 0.


Example usage:

To configure instance id 2 to add VID 10:


81

DGS3100# config stp instance_id 2 add_vlan 10

Success.

DGS3100#

To remove VID 10 from instance id 2:

DGS3100# config stp instance_id 2 remove_vlan 10

Success.

DGS3100#

config stp priority

Purpose To update the STP instance configuration.

Syntax config stp priority <value 0-61440> instance_id <value 0-15>

Description The config stp priority command updates the STP instance configuration settings on the Switch. The MSTP uses the priority in selecting the root bridge, root port and designated port. Assigning higher priorities to STP regions instructs the Switch to give precedence to the selected instance_id for forwarding packets. A lower value indicates a higher priority.

Parameters priority <value 0-61440> - The priority for a specified instance_id for forwarding packets. The value may be between 0 and 61440, and must be divisible by 4096. A lower value indicates a higher priority.

instance_id <value 0-15> - The value of the previously configured instance id for which the user wishes to set the priority value. An instance_id of 0 denotes the default instance_id (CIST) internally set on the Switch.


Example usage:

To set the priority value for instance_id 2 as 4096:

DGS3100# config stp priority 4096 instance_id 2

Success.

DGS3100#

config stp mst_config_id

Purpose To update the MSTP configuration identification.

Syntax config stp mst_config_id [revision_level <int 0-65535> | name <string>]

Description The config stp mst_config_id command uniquely identifies the MSTP configuration currently configured on the Switch. Information


82

entered here is attached to BDPU packets as an identifier for the MSTP region to which it belongs. Switches having the same revision_level, name and identical vlans mapped for STP instance_ids are considered to be part of the same MSTP region.

Parameters revision_level <int 0-65535>– The MSTP configuration revision number. The value may be between 0 and 65535. This value, along with the name and identical vlans mapped for STP instance_ids identifies the MSTP region configured on the Switch. The default setting is 0.

name <string> - A string of up to 32 alphanumeric characters to uniquely identify the MSTP region on the Switch. This name, along with the revision_level value and identical vlans mapped for STP instance_ids identifies the MSTP region configured on the Switch. If no name is entered, the default name is the MAC address of the device.


Example usage:

To configure the MSTP region of the Switch with revision_level 10 and the name ‘Trinity’:

DGS3100# config stp mst_config_id revision_level 10 name Trinity

Success.

DGS3100#

config stp mst_ports

Purpose To update the port configuration for a MSTP instance.

Syntax config stp mst_ports [<portlist> | <ch1-32>] instance_id<value 0-15> {internalCost [auto | value 1-200000000] | priority <value 0-240>}

Description The config stp mst_ports command updates the port configuration for a STP instance_id. If a loop occurs, the MSTP function uses the port cost to select an interface to put into the forwarding state (if the switch isn’t Root). If the switch is Root, then higher priority value for interfaces will influence on selected ports to be forwarding first at connected network devices. In instances where the priority value is identical, the MSTP function implements the lowest port number into the forwarding state and other interfaces are blocked. Remember that lower priority values mean higher priorities for forwarding packets.

Parameters <portlist> – A port or range of ports to be configured. The port list is specified by listing switch number and the beginning port number on that switch, separated by a colon. Then the highest port number of the range is specified. The beginning and end of the port list range are separated by a dash. For example, 1:3 specifies switch number 1, port 3. 1:22 specifies switch number 1, port 22. 1:3-22 specifies all of the ports of switch 1, between port 3 and port 22 − in numerical order.


instance_id <value 0-15> - The value may be between 0 and 15. An entry of 0 denotes the CIST (Common and Internal Spanning Tree.


83

internalCost – The relative cost of forwarding packets to specified ports when an interface is selected within an STP instance. The default setting is auto. There are two options:

auto – Specifies setting the quickest route automatically and optimally for an interface. The default value is derived from the media speed of the interface.

value 1-200000000 – Specifies setting the quickest route when a loop occurs. The value may be in the range of 1-200000000. A lower internalCost represents a quicker transmission.

priority <value 0-240> - The priority for the port interface The value may be between 0 and 240. A lower number denotes a higher priority. A higher priority designates the interface to forward packets first.


Example usage:

To designate ports 1 through 5 on module one, with instance ID 2, to have an auto internalCost and a priority of 16:

DGS3100# config stp mst_ports 1:1-5 instance_id 2 internalCost auto priority 16

Success.

DGS3100#

config fdb aging_time

Purpose To set the aging time of the forwarding database.

Syntax config fdb aging_time <value 10-630>

Description The config fdb aging_time command sets the aging time of the forwarding database. The aging time affects the learning process of the Switch. Dynamic forwarding table entries, which are made up of the source MAC addresses and their associated port numbers, are deleted from the table if they are not accessed within the aging time. The aging time can be from 0 to 630 minutes with a default value of 5 minutes. A very long aging time can result in dynamic forwarding table entries that are out-of-date or no longer exist. This may cause incorrect packet forwarding decisions by the Switch. If the aging time is too short however, many entries may be aged out too soon. This will result in a high percentage of received packets whose source addresses cannot be found in the forwarding table, in which case the Switch will broadcast the packet to all ports, negating many of the benefits of having a Switch.

Parameters <value 0-630> − The aging time for the MAC address forwarding database value, in minutes.


Example usage:

To set the fdb aging time:

DGS3100# config fdb aging_time 300

config scheduling

Purpose To configure traffic scheduling for each of the Switch’s QoS queues.

Syntax config scheduling <class_id 0-3> max_packet <value 0-15>

Description The config scheduling command configures traffic scheduling for each of the Switch’s QoS queues.

The Switch contains four hardware classes of service. Incoming packets must be mapped to one of these four hardware queues. This command is used to specify the rotation by which these four


96

hardware queues are emptied.

The Switch’s default (if the config scheduling command is not used) is to empty the hardware queues in order – from the highest priority queue (hardware class 3) to the lowest priority queue (hardware class 0). Each hardware queue transmits all of the packets in its buffer before allowing the next lower priority queue to transmit its packets. When the lowest hardware priority queue has finished transmitting all of its packets, the highest hardware priority queue can again transmit any packets it may have received.

The max_packets parameter allows the user to specify the maximum number of packets a given hardware priority queue can transmit before allowing the next lowest hardware priority queue to begin transmitting its packets. A value between 0 and 15 can be specified. For example, if a value of 3 is specified for all the queues, then the highest hardware priority queue (number 3) will be allowed to transmit 3 packets – then the next lowest hardware priority queue (number 2) will be allowed to transmit 3 packets, and so on, until all of the queues have transmitted 3 packets. The process will then repeat.

Parameters <class_id 0-3> − The hardware classes of service to which the config scheduling command is to be applied. The four hardware classes of service are identified by number (from 0 to 3) with class 3 having the highest priority.

max_packet <value 0-15> − Specifies the maximum number of packets the above specified priority class of service is allowed to transmit before allowing the next lower priority class of service to transmit its packets. The value may be between 0 and 15 packets. The default value is 1 for class_id 0, 2 for class_id 1, 4 for class_id 2, and 8 for class_id 3.

Restrictions Only administrator or operator level users can issue this command. This command is usable only if the device was configured to work in round robin scheduling (config scheduling_mechnism)

Example usage:

To configure traffic scheduling:

DGS3100# config scheduling 3 max_packet 15

Success.

DGS3100#

show scheduling

Purpose To display the currently configured traffic scheduling on the Switch.

Syntax show scheduling

config scheduling_mechanism

Purpose To configure the scheduling mechanism for the QoS function.

Syntax config scheduling_mechanism <class_id 0-3> [strict | round_robin]

Description The config scheduling_mechanism command configures the scheduling mechanism for the QoS function. It allows the user to select between a round robin (WRR) and a strict mechanism for emptying the priority classes of service of the QoS function. The Switch contains four hardware priority classes of service. Incoming packets must be mapped to one of these four hardware priority classes of service, or queues. This command is used to specify the rotation by which these four hardware priority queues are emptied.

The Switch’s default is to empty the four hardware priority queues in order − from the highest priority hardware queue (class 3) to the lowest priority hardware queue (class 0). Each queue will transmit all of the packets in its buffer before allowing the next lower priority queue to transmit its packets. A lower priority hardware queue will be pre-empted from emptying its queue if a packet is received on a higher priority hardware queue. The packet received on the higher priority hardware queue transmits its packet before allowing the lower priority hardware queue to resume clearing its queue.

Parameters <class_id 0-3> – This specifies to which of the four hardware classes of service the config scheduling_mechanism command applies. The four hardware classes of service are identified by number (from 0 to 3), with the 0 queue having the lowest priority.

strict – Specifies that the highest class of service is the first to be


102

processed. That is, the highest class of service should finish emptying before the others begin.

round_robin – Specifies that the priority classes of service are to empty packets in a weighted roundrobin (WRR) order.

Purpose To globally enable MAC based access control.

Syntax enable mac_based_access_control

Description The enable mac_based_access_control command enables the functionality of MAC-based access control globally on the switch.

This command also enables 802.1x globally if it is disabled, as 802.1x functionality is used to activate MAC authentication.

If ports on the switch are configured to MAC-based mode, this command sets the port state to auto. To achieve this, the enable command runs the following 802.1x command on these ports:

- config 802.1x auth_parameter ports 1:2 port_control auto

Parameters None.

Restrictions None.

Example usage:

To enable MAC Based Access Control:

DGS3100# enable mac_based_access_control

148

disable mac_based_access_control

Purpose To globally disable MAC based access control.

Syntax disable mac_based_access_control

Description The disable mac_based_access_control command disables the functionality of MAC-based access control globally on the switch.

This command disables 802.1x if it is enabled, as 802.1x functionality is used to activate MAC authentication.

However, if ports activated to the standard ‘Port Based 802.1x’ exist, 802.1x is not disabled globally, and only the MAC Based authentication configured ports move to a ‘Forced Authorized’ state.

Parameters None.

Restrictions None.

Example usage:

To disable MAC Based Access Control:

DGS3100# disable mac_based_access_control

DGS3100#

config mac_based_access_control

Purpose To enable/disable MAC based access control on a port(s).

Syntax config mac_based_access_control {ports [<portlist> | all] state [enable | disable] }

Description The config mac_based_access_control command enables or disables the functionality of MAC-based access control on a port(s).

When using command to enable functionality:

This command enables 802.1x on the port(s), as 802.1x functionality is used to activate MAC authentication. This command also configures RADIUS as the authenticating protocol for 802.1x. To achieve this, the enable command runs the following 802.1x commands:

- config 802.1x auth_parameter ports 1:2 enable_reauth enable


- config 802.1x auth_mode mac_base ports 1:2

- config 802.1x auth_protocol radius

Important note: In order to complete the activation of MAC authentication, the related ports must be configured as members in the guest VLAN.

When using this command to disable functionality on a port or ports, this command returns the port(s) to the default settings. To achieve this, the disable command removes the following commands (configured by the enable command) from port:

- config 802.1x auth_parameter ports 1:2 enable_reauth enable


- config 802.1x auth_mode mac_base ports 1:2

Parameters <portlist> − A port or range of ports whose MAC authentication is enabled/disabled on it.

create authen_login method_list_name

Purpose To create a user-defined list of authentication methods for users logging on to the Switch.

Syntax create authen_login method_list_name <string 12>

Description The create authen_login method_list_name command creates a list of authentication techniques for user login. The Switch can support up to eight method lists, but one is reserved as a default and cannot be deleted. Multiple method lists must be created and configured separately.

Parameters <string 12> - Defines the method_list_name to be created as a string of up to 12 alphanumeric characters.


Example usage:

To create the method list ‘Trinity’:

DGS3100# create authen_login method_list_name Trinity

Success.

DGS3100#

config authen_login

Purpose To configure a user-defined or default method list of authentication methods for user login.

Syntax config authen_login [default | method_list_name <string 12>| http_method_list | https_method_list] method {tacacs+ | radius | local | none}

Description The config authen_login command configures a user-defined or default method list of authentication methods for users logging on to the Switch. The sequence of methods implemented in this command affects the authentication result. For example, if a user enters a sequence of methods like tacacs – local, the Switch sends an authentication request to the first tacacs host in the server group. If no response comes from the server host, the Switch sends an authentication request to the second tacacs host in the server group and so on, until the list is exhausted. When the local method is used, the privilege level is dependant on the local account privilege configured on the Switch.

Successful login using any of these methods gives the user a ‘user’ priviledge only. If the user wishes to upgrade his or her status to the administrator level, the user must implement the enable admin command, followed by a previously configured password. (See the enable admin part of this section for more detailed information, concerning the enable admin command.)

Parameters default – The default method list for access authentication, as defined by the user. The user may choose one or more of the following authentication methods:

tacacs+ – Specifies that the user is to be authenticated using the TACACS+ protocol from the remote TACACS+ server hosts of the TACACS+ server group list.


radius - Specifies that the user is to be authenticated using the RADIUS protocol from the remote RADIUS server hosts of the RADIUS server group list.

local - Specifies that the user is to be authenticated using the local user account database on the Switch.

none – Specifies that no authentication is required to access the Switch.

http_method_list – Specifies the httpsmethod list for access authentication.

https_method_list – Specifies the https method list for access authentication.

method_list_name <string 12> – Specifies a previously created method list name defined by the user. One or more of the following authentication methods may be added to this method list:

tacacs+ – Specifies that the user is to be authenticated using the TACACS+ protocol from a remote TACACS+ server.

radius - Specifies that the user is to be authenticated using the RADIUS protocol from a remote RADIUS server.

local - Specifies that the user is to be authenticated using the local user account database on the Switch.


NOTE: Entering none or local as an authentication protocol overrides any other authentication that follows it on a method list or on the default method list.


Example usage:

To configure the user defined method list ‘Trinity’ with authentication methods TACACS+, RADIUS and local, in that order.

DGS3100# config authen_login method_list_name Trinity method tacacs+ radius local

Success.

DGS3100#

delete authen_login method_list_name

DGS3100#

create authen_enable method_list_name

Purpose To create a user-defined method list of authentication methods for promoting normal user level privileges to Administrator level privileges on the Switch

Syntax create authen_enable method_list_name <string 12>

Description The create authen_enable method_list_name command creates a list of authentication methods for promoting users with normal level privileges to Administrator level privileges using authentication methods on the Switch. Once a user acquires normal user level privileges on the Switch, he or she must be authenticated by a method on the Switch to gain administrator privileges on the Switch,


186

which is defined by the Administrator. A maximum of eight (8) enable method lists can be implemented on the Switch.

Parameters <string 12> - Defines the authen_enable method_list_name to be created as a string of up to 12 alphanumeric characters.


Example usage:

To create a user-defined method list, named ‘Permit’ for promoting user privileges to Adminstrator privileges:

config authen_enable

Purpose To configure a user-defined method list of authentication methods for promoting normal user level privileges to Administrator level privileges on the Switch.

Syntax config authen_enable [default | method_list_name <string 12>] method {tacacs+ | radius | local_enable | none}

Description The config authen_enable command configures a user-defined list of authentication methods for promoting normal user level privileges to Administrator level privileges using authentication methods on the Switch. Once a user acquires normal user level privileges on the Switch, he or she must be authenticated by a method on the Switch to gain administrator privileges on the Switch, which is defined by the Administrator. A maximum of eight (8) enable method lists can be implemented simultaneously on the Switch.

The sequence of methods implemented in this command affects the authentication result. For example, if a user enters a sequence of methods like tacacs+ – radius – local_enable, the Switch sends an authentication request to the first TACACS+ host in the server group. If no verification is found, the Switch sends an authentication request to the second TACACS+ host in the server group and so on, until the list is exhausted. At that point, the Switch restarts the same sequence with the following protocol listed, radius. If no authentication takes place using the radius list, the local_enable password set in the Switch is used to authenticate the user.

Successful authentication using any of these methods gives the user an ‘Admin’ level privilege.

Parameters default – The default method list for adminstration rights authentication, as defined by the user. The user may choose one or more of the following authentication methods:

tacacs+ – Specifies that the user is to be authenticated using the TACACS+ protocol from the remote TACACS+ server hosts of the TACACS+ server group list.

radius – Specifies that the user is to be authenticated using the RADIUS protocol from the remote RADIUS server hosts of the RADIUS server group list.

local_enable - Specifies that the user is to be authenticated


187

using the local user account database on the Switch.


method_list_name <string 12> – Specifies a previously created authen_enable method_list_name. The user may add one or more of the following authentication methods to this method list:

tacacs+ – Specifies that the user is to be authenticated using the TACACS+ protocol from a remote TACACS+ server.

radius - Specifies that the user is to be authenticated using the RADIUS protocol from a remote RADIUS server.

local_enable - Specifies that the user is to be authenticated using the local user account database on the Switch. The local enable password of the device can be configured using the ‘config admin local_password’ command.



Example usage:

To configure the user defined method list ‘Permit’ with authentication methods TACACS+, RADIUS and local_enable, in that order.

DGS3100# config authen_enable method_list_name Trinity method tacacs+ radius local_enable

Success.

Purpose To create an authentication server host.

Syntax create authen server_host <ipaddr> protocol tacacs+ {port <int 1-65535> | key [<key_string 128> | none] | timeout <int 1-30>} priority [first | second | third}

Description The create authen server_host command creates an authentication server host for the TACACS+/RADIUS security protocols on the Switch. When a user attempts to access the Switch with authentication protocol enabled, the Switch sends authentication packets to a remote TACACS+/RADIUS server host on a remote host. The TACACS+/RADIUS server host then verifies or denies the request and returns the appropriate message to the Switch. More than one authentication protocol can be run on the same physical server host but, remember that TACACS+/RADIUS are separate entities and are not compatible with each other. The maximum supported number of server hosts is 16.

Parameters server_host <ipaddr> – The IP address of the remote server host to add.

protocol – The protocol used by the server host. The options are:

tacacs+ – Specifies that the server host utilizes the TACACS+ protocol.

radius – Specifies that the server host utilizes the RADIUS protocol.

port <int 1-65535> – The virtual port number of the authentication protocol on a server host. The value must be between 1 and 65535. The default port number is 49 for TACACS/TACACS+ servers and 1812 and 1813 for RADIUS servers but the user may set a unique port number for higher security.

key [<key_string 128> | none] – The authentication key to be shared with a configured TACACS+ or RADIUS server only. The value is a string of up to 128 alphanumeric characters, or none.

timeout <int 1-30> – The time in seconds the Switch waits for the server host to reply to an authentication request. The default value is 5 seconds.

retransmit <int 1-10> – The number of times the device resends an authentication request when the server does not respond. The value is between 1 and 10. This field is inoperable for the TACACS+ protocol.


Example usage:

local_enable admin

Purpose To promote user level privileges to administrator level privileges.

Syntax local_enable admin

Description The local_enable admin command enables a user to be granted administrative privileges on to the Switch. After logging on to the Switch, users have only ‘user’ level privileges. To gain access to administrator level privileges, the user may enter this command. The system then prompts for an authentication password. Possible authentication methods for this function include TACACS, TACACS+, RADIUS, user defined server groups, local enable (local account on the Switch), or no authentication (none). Because TACACS does not support the enable function, the user must create a special account on the server host which has the username ‘enable’, and a password configured by the administrator that will support the ‘enable’ function. This function becomes inoperable when the authentication policy is disabled.

Parameters None.


Example usage:

To enable administrator privileges on the Switch:

DGS3100# local_enable admin

Password: ******

DGS3100#


Purpose To configure the local_enable password for administrator level privileges.

Syntax config admin local_enable

Description The config admin local_enable command changes the locally enabled password for the local_enable admin command. When a user chooses the ‘local_enable’ method to promote user level privileges to administrator privileges, the user is prompted to enter the password configured here.

After entering the config admin local_enable command, the user is prompted to enter the old password, then a new password in a string


194

of no more than 15 alphanumeric characters, and finally prompted to enter the new password again for confirmation. See the example below.

Parameters None.


Example usage:

To configure the password for the ‘local_enable’ authentication method.

show poe


config poe

Purpose To configure the parameters for the whole PoE system.

Syntax config poe box_id <value 1-6> system_power_limit [ps1 | ps2 | ps3] disconnect_method [deny_next_port | deny_low_priority_port]

Description The config poe command configures the parameters for the PoE system on a unit member of the stack.

Parameters box_id <value 1-6> – The unit’s current stack membership number.

system_power_limit [ps1 | ps2 | ps3] – Specifies the power budget of the whole PoE system, according to the type of power supply used (ps1, ps2, ps3).

disconnect_method – Configures the power management disconnection method. When the total consumed power exceeds the power budget, the PoE controller initiates a port disconnection to prevent overloading the power supply. The controller uses one of the following two ways to implement the disconnection:

deny_next_port – After the power budget has been exceeded, the next port attempting to power up is denied, regardless of its priority. This is the default setting.

deny_low_priority_port – After the power budget has been exceeded, the next port attempting to power up, causes the port with the lowest priority to shut down (to allow high-priority ports to power up).


Example usage:

To config the PoE System on the Switch:

DGS3100# config poe system_power_limit 300 disconnect_method deny_next_port


209

Success.

Purpose To configure the PoE port settings.

Syntax config poe ports<portlist> { state [enable {time_range <range_name 32>} | disable] | priority [ low | high | critical ] | power_limit <value 1-15400>}

Description The config poe ports command configures PoE settings for a port or range of ports.

Parameters <portlist> – A port or range of ports to be configured or all the ports.

state – Enables or disables the PoE function on the Switch.

time_range <range_name 32> – specify the time range name to be assigned to this POE configuration. To remove the time range from a port configure the same command without the time range.

priority – Setting the port priority affects power-up order and shutdown order. Power-up order: When the Switch powers-up or reboots, the ports are powered up according to their priority (critical first, then high and finally low). Shutdown order: When the power limit has been exceeded, the ports will shut down according to their priority if the power disconnect method is set to deny_ low_priority_port. The possible options are:

critical – Specifies that these ports have the highest priority for all configured PoE ports. These ports will be the first ports to receive power and the last to disconnect power.

high – Specifies that these ports have the second highest priority for receiving power and shutting down power.

low – Specifyies that these ports have the lowest priority for receiving and shutting down power. These ports will be the first ports to have their power disconnected if the power_disconnect_method chosen in the config poe command is deny_low_priority_port.

power_limit <value 1-15400> – Specifies the per-port power limit. If a port exceeds 10% of its power limit, the PoE system will shut down that port. The minimum user-defined setting is 1 mW and the maximum is 15400 mW. The default setting is 15400 mW.


Example usage:

To config the Switch’s ports for PoE:

DGS3100# config poe ports 1-3 state enable priority critical power_limit 12000

Command Parameter

traceroute {ipv4-address | hostname} [size 40-1472] [ttl 1-255] [count 1-10] [timeout 1-60] [source ip-address] [tos 0-255]


traceroute

Purpose Used to discover the routes packets actually take when traveling to their destination.

Syntax traceroute {ipv4-address | hostname} [size 40-1472] [ttl 1-255] [count 1-10] [timeout 1-60] [source ip-address] [tos 0-255]

Description The traceroute command takes advantage of the error messages generated by the devices when a datagram exceeds its time-to-live (TTL) value.

The traceroute command starts by sending probe datagrams with a TTL value of one. This causes the first device to discard the probe datagram and send back an error message. The traceroute command sends several probes at each TTL level and displays the round-trip time for each.

The traceroute command sends out one probe at a time. Each outgoing packet may result in one or two error messages. A ‘time exceeded’ error message indicates that an intermediate device has seen and discarded the probe. A ‘destination unreachable’ error message indicates that the destination node has received the probe and discarded it because it could not deliver the packet. If the timer goes off before a response comes in, the traceroute command prints an asterisk (*).

The traceroute command terminates when the destination responds, when the maximum TTL is exceeded or when the user interrupts the trace by pressing Esc.

Parameters ipv4-address – Specifies the IP address of the destination host.hostname – Defines the host name of the destination host. (Range: 1-158 characters). packet_size - Defines the number of bytes in a packet. (Range: 40-1472).

max-ttl - Defines the largest TTL value that can be used. The traceroute command terminates when the destination is reached or when this value is reached. (Range:1-255)

packet_count - The number of probes to be sent at each TTL level. (Range:1-10)time_out - Specifies the number of seconds to wait for a response to a probe packet. (Range:1-60) source ip-address - Specifies one of the device’s interface addresses to use as a source address for the probes. The device normally selects what it feels is the best source address to use.


227

Tos - Specifies the Type-Of-Service byte in the IP Header of the packet. (Range: 0-255)


Example usage:

To discover the routes packets take when traveling to their destination:
